Mjölnir (commonly written without diacritics as Mjolnir) and Stormbreaker, in the Marvel Cinematic Universe (MCU), are sentient enchanted weapons of choice used by Thor. Both are melee weapons and were created out of Uru metal forged with the heat of a dying star in the Dwarven kingdom of Nidavellir, with the assistance of the dwarf king and master weapon-maker Eitri. Mjolnir is a hammer, and was enchanted by Thor's father, Odin, so that only those the hammer deemed "worthy" are capable of wielding or even lifting it. Stormbreaker is an axe, and although it does not have such a worthiness enchantment, its power is such that a mere mortal attempting to wield it would be driven mad.
Mjolnir first appeared in the post-credits scene in Iron Man 2 (2010), and has appeared thereafter in every film featuring Thor except for one, those being Thor (2011), The Avengers (2012), Thor: The Dark World (2013), Avengers: Age of Ultron (2015), Doctor Strange (2016), Thor: Ragnarok (2017), Avengers: Endgame (2019), and Thor: Love and Thunder (2022). Stormbreaker first appears in Avengers: Infinity War (2018)—also the only MCU film in which Thor does not wield Mjolnir at all—and appears again in Avengers: Endgame, and Thor: Love and Thunder. Conversely, the post-credit scene in Iron Man 2 and a scene from the second episode of the Disney+ TV series What If...? are the only MCU media in which Mjolnir appears while Thor does not.
